IP Environment Check

See what a site sees when you connect

Your exit IP, its purity grade, the network behind it, and the browser signals that give a proxy away. All in one pass.

Check this connection

Runs against whatever you are connected through right now. Nothing runs until you click.

FAQ

Frequently asked questions

Five things at once: the IP your traffic exits from, the purity grade we hold for it, whether the owning network is a consumer ISP or a hosting company, whether your browser timezone and language line up with the location of the IP, and whether WebRTC reports a different address than your HTTP traffic.

IPScanner

Why Choose IPScanner

Teams use IPScanner to tell real users apart from masked and automated traffic.

  • Accuracy you can measure

    Verdicts come with a 0 to 100 confidence score, so you tune the threshold to your own risk instead of trusting one number.

  • Built to scale

    The API runs on infrastructure sized for production traffic, with a 99.9% uptime target for business-critical use.

  • Data that stays fresh

    We refresh VPN, proxy, and Tor lists continuously, so newly spun-up servers get caught quickly.

  • Easy to wire in

    A plain REST API works with any language or framework. Most teams are live the same afternoon.

  • Documentation that's honest

    Worked examples in curl, JavaScript, and Python, plus straight notes on what each signal does and doesn't mean.

  • People who know the domain

    Support comes from engineers who work on IP detection every day, not a generic help desk.
